Connecticut Deal Landscape 2025-2026
CT deal activity in 2025 was bifurcated: large-cap take-privates ran hot (Apollo/Barnes $3.6B, Stanley Black & Decker/CAM $1.8B, Travelers Canada $2.4B), while LMM deal count tracked the national pattern of H1 decline before H2 recovery. The dominant buyer type is private equity, led by the Greenwich/Stamford/Westport sponsor cluster. The biggest driver is founder-generational ownership transitions combined with $1T+ of PE dry powder.
PE Take-Privates of CT Industrial Champions
Apollo closed $3.6B Barnes Group, Arcline completed $1.8B Kaman at ~16x EBITDA, and Stanley Black & Decker is divesting CAM to Howmet for $1.8B. PE is paying mid-teens multiples for proprietary, aftermarket-heavy CT platforms.
Greenwich-Led Insurance Mega-Recaps
Stone Point closed Trident X at $11.5B, then led the $7B+ OneDigital recap with CPP Investments. Fairfield County is ground zero for broker consolidation even as overall deal count fell to a four-year low.
Strategic Portfolio Pruning
Travelers sold Canadian P&C for $2.4B at 1.8x book. Cigna completed $3.7B Medicare sale. RTX sold Simmonds Precision to TransDigm for $765M. CT anchors are aggressively reshaping portfolios.
CT-Native Sponsor LMM Roll-ups
Gemspring, Heartwood ($1.4B AUM), Altus, Hamilton Robinson, Charter Oak, Clearview, and Gainline ($400M Fund II) drive tuck-in volume across specialty manufacturing, business services, and healthcare.

Connecticut Tax & Deal Structure
Connecticut sits among the higher-tax Northeastern states for M&A sellers: personal income taxed up to 6.99% with no preferential capital gains rate, a standalone estate and gift tax, and the only state imposing a controlling interest transfer tax on indirect real estate transfers.
State Income Tax / PET
NeutralCT imposes progressive rates from 2% to 6.99% on income above $500K/$1M. The Pass-Through Entity Tax became elective in 2024, providing a SALT-cap workaround at 6.99% with an 87.5% member credit. Well-timed PET elections preserve federal SALT-cap benefit on transaction-year income.
Capital Gains Treatment
UnfavorableConnecticut taxes capital gains as ordinary income at the same 2-6.99% rates. Combined with federal 20% LTCG plus 3.8% NIIT, CT-resident founders face an all-in rate of roughly 30.8% on non-QSBS gain — among the highest in the Northeast.
QSBS Section 1202 Conformity
FavorableCT conforms to federal QSBS exclusion because the income tax starts from federal AGI. Post-OBBBA, tiered 50/75/100% exclusion at 3/4/5 years with $15M per-issuer cap and $75M gross-asset ceiling. For CT tech and defense founders, the single most powerful planning tool.
Asset vs. Stock Sale
UnfavorableCT imposes 6.35% sales and use tax on tangible personal property in asset sales. Buyers must submit Form AU-866 for Tax Clearance Certificate (60-day DRS window). Real estate conveyance tax adds 0.75-2.25% on property transfers. Stock sales avoid most friction.
Estate & Succession Tax
NeutralCT has a $13.99M (2025) / $15M (2026) exemption matching federal, with a flat 12% rate and $15M total liability cap. CT is the only state with a standalone gift tax. No spousal portability means pre-exit SLATs, GRATs, and non-grantor trusts are critical above $15M net worth.
Controlling Interest Transfer Tax (CITT)
UnfavorableUnder CGS §12-638b, CT imposes a 1.11% tax on sale of >50% controlling interest in entities owning CT real property. Tax is on full FMV unreduced by mortgages. For a $50M Hartford office building, the stealth tax alone is $555,000. Not credited against regular conveyance tax.

88-93%The Challenge
Dual key-person risk: the founder-CEO personally underwrote ~40% of top accounts and the Chief Actuary was viewed as indispensable. The transaction required CT Insurance Department Form A approval under CGS §38a-130, including pre-acquisition Form E analysis, biographical affidavits, and a public hearing.
The Process
- 1Separated the MGA (non-regulated, higher-multiple) from the carrier (regulated) to enable dual-track interest and optimize CITT analysis on Hartford HQ
- 2Approached 14 strategic buyers plus three family offices; secured five IOIs from national carriers, Bermuda specialty groups, and PE-backed platforms with existing CT Form A approvals
- 3Negotiated 3-year retention for founder and Chief Actuary with rollover equity; structured pre-closing PET election and QSBS gifting to non-grantor trusts
- 4Coordinated Form A filing and public hearing, secured DRS Form AU-866 clearance on MGA assets, filed CITT on indirect Hartford real estate transfer

Key Lessons
- CT Form A timing drives the deal clock — pre-file informal drafts and line up biographical affidavits before signing LOI to avoid 60-120 day surprises
- CITT is a stealth cost in every CT deal touching real estate — even on pure stock sales, the 1.11% tax on FMV can reach seven figures; model it early
- Pair CT PET elections with federal QSBS planning — PET captures SALT-cap benefit on transaction-year ordinary income while §1202 shelters up to $15M of C-corp gain
